Rock glaciers in the Ulakhan-Chistay ridge (axial part of the Chersky mountain range)

open access: yesЛëд и снег, 2019
The Ulakhan-Chistay Ridge is interesting by the fact that one of the most extensive mountain glaciations in northeast Russia is located here. In addition, there are widespread specific glacial-cryogenic formations  – stone glaciers related to glacial and

The study of the ground freezing method using natural cold to protect the foundation pit from groundwater inflow

open access: yesИнженерно-строительный журнал, 2015
When the bottom of the foundation pit is below the groundwater level, groundwater drawdown is required; as a rule, it is extremely expensive. In order to reduce water drawdown costs in areas with consistently low air temperatures we suggest to excavate ...

Greenhouse gas balance over thaw-freeze cycles in discontinuous zone permafrost [PDF]

open access: yes, 2017
Peat in the discontinuous permafrost zone contains a globally significant reservoir of carbon that has undergone multiple permafrost-thaw cycles since the end of the mid-Holocene (~3700 years before present).

Permafrost temperature and active-layer thickness of Yakutia with 0.5-degree spatial resolution for model evaluation [PDF]

open access: yesEarth System Science Data, 2013
Based on the map of landscapes and permafrost conditions in Yakutia (Merzlotno-landshaftnaya karta Yakutskoi0 ASSR, Gosgeodeziya SSSR, 1991), rasterized maps of permafrost temperature and active-layer thickness of Yakutia, East Siberia were derived.

Mapping Mountain Permafrost Landscapes in Siberia Using Landsat Thermal Imagery

open access: yesGeosciences, 2018
Intensive development of South Yakutia, a mountainous area in the Russian sporadic permafrost zone, must be founded on knowledge about regional permafrost conditions. New permafrost maps for mountainous areas in South Yakutia (the Elkon Mountains and the

Climate and Permafrost Shifts in Yakutia’s Arctic and Subarctic from 1965 to 2023

open access: yesLand
By analyzing the last 50–60 years of climate changes in Arctic and Subarctic Yakutia, we have identified three distinct periods of climate development.

Fast response of cold ice-rich permafrost in northeast Siberia to a warming climate

open access: yesNature Communications, 2020
Siberian Arctic permafrost contains vast stores of carbon, the fate of which is dependent on the climate. Here the authors use models of future scenarios to show that under the direst climate changes up to 2/3 of the stored organic carbon could thaw.

Influence of Rainfall Changes on the Temperature Regime of Permafrost in Central Yakutia

open access: yesLand, 2021
Climate change effects, such as melting of glaciers and sea ice in response to rising temperatures, may lead to an increase in global water availability and thus in precipitation.

Energy input is primary controller of methane bubbling in subarctic lakes [PDF]

open access: yes, 2014
Emission of methane (CH4) from surface waters is often dominated by ebullition (bubbling), a transport mode with high‐spatiotemporal variability. Based on new and extensive CH4 ebullition data, we demonstrate striking correlations (r2 between 0.92 and 0 ...
